Order Hymenoptera, Family Braconidae
- This page contains pictures and information about Braconid Wasps in subfamily Opiinae
found in the Brisbane area, Queensland, Australia.
- Wasps in this Subfamily Opiinae are small in size. They are often orange or yellow
in colours. Most of them parasitic on larvae of fruit flies.
- Fruit fly Parasitoid 1
- ? Opius sp., body length 4mm
- We found this Braconid Wasp on the fruits of Wild Tobacco (Solanum mauritianum).
Those Wild Tobacco plants are common weeds along creeks in Brisbane. Most of
the Wild Tobacco fruits were infected by a kind
of small fruit
flies. There were the wound on the fruits, if we open it we will
see the small fruit fly larvae. Sometimes we saw this small wasp, examining the infected fruits.
The wasp will insert her ovipositor into the wound. We believed she laid eggs
which the larvae will hatch and parasite on the fruit fly larvae. Please
also check this web page.
- Fruit fly Parasitoid 2
- ? Opius sp., body length 3mm
- We have a plum plant in our backyard. Some fruits were infected by a kind
of small fruit
flies Tephritidae. There were the wound on the fruits, if we open it we will
see the small fruit fly larvae. Sometimes we saw the small wasp, as the about
pictures, examining the infected fruits. After checking the wound on the fruit,
the wasp will insert her ovipositor into the wound. We believed she laid eggs
which the larvae will hatch and parasite on the fruit fly larvae.
